 Stud Bolts' Coating

Stud bolts can be coated to increase the resistance to corrosion. The most common types of coatings for stud bolts are listed below:

• Electro zinc plating
• Electro cadmium plating
• Hot dip galvanizing
• PTFE Coating
• Phosphate coating
• Electroless nickel plating
• Zinc-nickel coating
• Aluminum coating
• Silver coating
• Zinc/Nickel by electrodeposition
• Xylan coating

One of the most notable features of the PTFE Coated Hex Bolt is its exceptional resistance to corrosion. The PTFE (polytetrafluoroethylene) coating provides a protective barrier, shielding the bolt from harsh environmental conditions such as exposure to chemicals, moisture and extreme temperatures. This is of particular importance in the oil and gas industry, where components are often exposed to corrosive substances that can cause premature failure.

The use of PTFE Coated Hex Bolts has been shown to have a significant impact on the longevity of pipeline systems. The corrosion-resistant properties of this bolt enhance its durability and reduce maintenance costs over time. This makes it a cost-effective solution for companies looking to optimise their operations while ensuring the safety and reliability of their infrastructure.

Versatile Applications

The PTFE Coated Hex Bolt has been engineered for a broad spectrum of applications within the oil pipeline industry. Its versatility makes it suitable for various projects, including the construction of new pipelines, repairs, and upgrades to existing systems. The bolt is available in sizes ranging from 1/2 to 4 inches, allowing for customisation based on specific project requirements.

The PTFE Coated Hex Bolt has been engineered to meet the diverse needs of the industry, whether you are working on offshore drilling platforms, onshore pipelines, or storage facilities. Its robust design and reliable performance make it an essential component for any oil pipeline project, ensuring that your systems operate smoothly and efficiently.
